Patented Nov. 11, 1930 CHABLESC. nnmwnnn-or WESTERVILLE, OHIO TYPE-WRITING MACHINE -App1ication fi1ed February 18,- 1927. Serial No. 169,167.

My invention relates to typewriting machines. It relates, more particularly, to a typewriting machine so constructed that its efiiciency as a typewriter will be materially increased while, at the same time, being adapted to ledger posting, bill and statement writing or simllar work, together with means for assisting in assembling the work sheets in operative position in the machine.

Heretofore typewriting machines adapte for use as a billing and bookkeeping machine have been so constructed as to be inapplicable for ordinary typewriting work. Further, these machines have not been adapted for billing, statement writing and ledger posting in the same operation. This has been due to the fact that ledger sheets are of a different size than those ordinarily used for billing and statements and, no means has been provided for maintaining various sized sheets in proper relation to each other while being 'assembled'in the machine. Also, all sheets have, heretofore, been inserted in a typewriting machine with a sliding action,

which action has a tendency to disarrange the sheets with respect to their desired re'las tive position to each other. I

The means for assisting in assembling the work sheets in proper posltion in the machine is generally known as a collating device andhas previously, in most instances, formed an integral part of the machine. Such an arrangementis bulky and, in'imany cases, un-

, desirable, due to the space required and the 11 time necessary to assemble a plurality of sheets and,'in some instances, only sheets of the same size may be conveniently used. Billing or ledger posting on a typewriter, not equipped with a collating device, is also 4;: undeslrable, due to the time expended f in arranging the sheets in the typewriter, the

dilficulty in keeping a'number of sheets in their proper position and the danger ,of crimping or otherwise distorting the-sheets. Furthermore, typewriters that have been equipped with collating devices have usually had their parts so arranged that it was undesirable or-even impossible to use them for ordinary typewriting work.

. One object of my invention is to provide a collating device for typewriters that does not destroy any feature had by the typewriter prior to this change.

Another object of my invention is to provide a device that, when attached, increases 5 the advantages of the typewriter in-that it will simultaneously complete several operations at the speed of an ordinary'typewriter.

Afurther object of my invention is to provide a device wherein the papers are 5 placed in the typewriterin writing positionand no further adjustment is necessary after the papers are once so placed.-

A still further object'of my invention is to provide a device wherein the sheets of 5 paper may be placed in the machine at any position desirable, with relation to one another, and held securely in that position while the platen of the typewriter is being lowered into operative relation to the papers.

A still further object of my invention is to provide a device that will facilitate removal of the papers from as-well as their insertion into the typewriter without revolving the platen and which will thereby eliminatethe danger of crimping or otherwise distorting the papers.

Other and further objects of my invention will appear from the following description and the preferred embodiment of my invention will be seen in the accompanying drawings wherein similar characters of reference 7 designate corresponding parts and wherein:

Figure 1 is a pers ective view showing a plurality of work sheets in writing position in. a typewriter embodying the features of my invention prior to removal of the clamp. I j Figure 2 is a perspective view showing the platen of the typewriter in raised posi- I the papers.

tion to facilitate insertion into or removal of Figure 3 is a perspective view ofthe opposite end of the typewriter shown in Figure 1 showing the changes necessary in the construction of the typewriter.

'drawings, I have shown a platen 1 that may be swung into or out of operative relation to the work sheets assembled in a typewriter.

The platen 1 shown in these figures is particularly adapted to a Royal ty ewriter, although not limited thereto, since y minor variations in the constructions. of the typewriter, such a platen may be adapted to use on any type of typewriter. This platen lis mounted 'on a platen frame 2, which is pivoted to the main typewriter frame 3, as "at 4-.- The swinging movement of the platen is governed by the slotted arm 5 having one 30- at 6, and the opposite end slidably attached, 'by a slot and pin construction, to the main endrigidly attached to the platen frame 2, as

typewriter frame 3, as at 7.

Pivotally mounted on/t he platen frame 2,

is the usual paper guide 8 .which' is adapted to keep the sheet or sheetsof paper from interfering with the typewriter mechanism,

The platen frame 2 also carries the usual line space lever 9 and the variable line spacer 10, on which the stop has been placed, as at 12', to permit the shaft- 12 to enter the slot 11.

The main typewriter frame 3 is slotted, as

. I at 11, to receive the shaft 12 on which the platen is mounted, Adapted to hold the platen shaft 12 in the slot 11 and the platen 1 in operative relation on the sheet. or sheets of paper, is the'catch 13 actuated by the spring 14. This spring-actuated catch is adapted to engage a lug 15 rigidly attached to'the main typewriter'frame 3. The movable platen frame 2 is provided with a rod.

16 which acts as a brace and strengthens the movable'platen frame.

- Figures 4 and 5 show the board 17. which.

is adapted to hold the sheet or sheets of paper in proper position with relation to the spring I clamp 20 prior to their being clamped togetherandinserted into the typewriter.

This board 17 is provided with thegro'oves 18 and grooved upright posts 19 to receive the springclamp 20 and hold it in proper position. The board 17 is also equipped with the paper guides 25. The clamp 20 is, preferably, of the form-shown in Figure 6 and consists of a flat portion having. a spring catch 21 and a flange 22 thereon and a flat spring portion 23 hinged thereto by the hinge 24.

It is preferable that two or more grooves 18 be provided in the board 17 so that, in adjusting the papers with relation to the spring clamp 20, held by one of the grooves, it will not be necessary to run the sheet or sheets ofi the board when the last entry on the sheet 1 or sheets is near the end of the sheet or sheets or, in other words, when an entry is made on the bottom of ,asheet. This is plainly shown-in Figure 4 of the drawings. This would also-be true if there were only one groovein the board and an entry was to be made near the top of-the sheet. 7

In operation, the-spring clamp 20 is placed in one of the grooves 18 of the board 17 and various sized sheets of paper are then placed on the board 17, as shown in Figure 4:. The papers are, preferably, marked withl-dotted lines or-numbers along their edges to facilitate correct arrangement of the sheets. When the papers have been properly arranged, the spring clamp 20 is closed, as shown in Figure 5, and the papers are ready for insertion into the typewriter. Bifurcated posts 26' have'been providedj'on the main typewriter frame to receive the flange 22 of the spring clamp 20 so that the papers will be held in proper position while the platen is being lowered. It is important that the rooves 18 and the guides 25' on the board 1 be absolutely true as regards proper relative position so that the papers, when placed in the clamp and typewriter, will be in position for writing and no .further adjustments of the papers will be necessary. After the papers have been placed in the typewriter and the movable platen has been brought into operative relation to the papers, the clamp 20 may be removed by releasing the spring catch 21 and placed upon the board 17 ready tovreceive further paper. 7

It willbe clearly obvious, by referring to the previous descri tion, that I have pro- ,vided a collating evice for a typewriter that does not destroy any feature or take away any advantage'had by the typewriter prior to this change. A typewriter, when equipped with my invention, will function identically the same as an ordinary typewriter, insofar as ordinary typewriting work is concerned, and willhave an added advantage in that it will complete simultaneously several operations at the speed of I an ordinary typewriter.

It will also be clearly obvious, by reference to the previous description, and. the drawings attached hereto, that I have provided a device wherein sheets of paper of various sizes may be placed in the typewriter in, an position, with relation to one another,

that is desired and that the papers may be so adjusted on the collating board that they will be in writing position, when clamped together and placed in the typewriter, requiring no adjustment after being placed in the typewriter.

Furthermore, it will be obvious that, by using a movable platen that may be moved into or out of operative relation with the work sheets in a typewriter, I have provided a device facilitating the removal of the papers from as Well as their insertion into the means pivotally mounted on said carriage at a point remote from the normal operating position of the platen to permit the platen to be moved to a position such as to uncover the space normally occupied by the platen when in operative relation.

2. In a typewriting machine, a movable carriage, a platen frame carrying a rotatable platen XZOllIltQd upon pivots at the rear of said carri ge, the mounting of saidplaten permitting the platen to be moved to a position such as to uncover the space normally occupied by the platen when in operative relation thereby enabling a work sheet to be positioned in said space.

3. In a typewriting machine, a movable carriage, a platen frame carrying a rotatable platen mounted upon pivots at the rear of said carriage, the mounting of said platen permitting the platen to be moved to a position such as to uncover the space normally occupied by the platen when in operative relation thereby 'enabling a horizontally disposed work sheet to be moved vertically into position in said space.

4. In a typewriting machine, a movable carriage, a platen frame carrying a rotatable laten mounted upon pivots at the rear of said carriage, the mounting of said platen permitting the platen to be moved through an arcuate path to a position such as to uncover the space normally occupied by the platen when in operative relation thereby enabling a work sheet to be positioned in said space.

5. In a typewriting machine, a movable carriage, a platen frame carrying a, rotatable platen pivotally mounted at the rear of said carriage, the mounting of said platen permitting the platen to be moved to a position such as to uncover the space normally occupied by the platen when in operative' position, removable means for holding the said work sheet, and means for maintainin said removable sheet holding means in sucii position with respect to said platen that further adjustment of the work sheet prior to writing after the platen has been moved into operative relation therewith is unnecessary, said maintaining means embodying supporting means mounted on said machine and spaced from said platen.

In testimony whereof I hereby aflix my signature.
